In carrying outthe present invention it is contemplated to employ anygeneral construction of wheel embodying the usual hub 1,.spokes 2, andfolly 3. The present invention relates primarily to the peculiar form ofthe resilient or spring tire or tread shown at Land-the special meansemployed for fastening the same to the felly 3. As shown most clearly inFig. 1 the tire 4 comprises a continuous coiled spring, the coilsinclining in one direction and consisting of an endless piece of wirebent into proper shape by a. forward coiling movement, so that the sideportions of the coil of thetire 4 at one side of the wheel are inadvance of the operative side portions.

In order to secure the tire 4 to the wheel,

on its outer side and in the channel of this member the innermostportions of the coiled spring comprising the tire 4 are received-orseated, being held in place by a band 6 which the telly 3 is providedwith a channel iron 5 passes through the coils as shown most clearlyi11-l igs,2 and Fastenings 7 secure the parts 4, 5, and 6 to the telly3; and these fastenings are of peculiar formation. The l'ast-enings 7consist of bolts having lockin heads 8 which are adapted to pass throughlongitudinal slots 9 in the band 6, and to be turned into positionstransverse or at a right angleto said slots .to therebyinterlockeffectively \Vltll the band (3 in order to connectthe latter with thetelly. A short distance below its head 8 each of the fastenings71isl'ornied with grooves 7* at opposite sides thereot'in which groovesthe lnner portior of coils of. the tire 4 are adapted tobe re- (mixed.The grooves 7? permit the'coils of the tire to lie in closerr'elationthan were the bolts 7 not. provided therewith. In forming the grooves 7in the fastening means 7 said members are subjected to pres- .suro fromopposite SKIES, andtlllS actlon fornis opposite shoulders on the sidesof the member opposite those havin the The shoulders 7 are a apted toengage the upper side of the channel Iron 5. and the lower side of theband 6 and in this manner the portions 7 constitute parts which spacethe band 6 from the channel iron, preventing the bolts 7 fromconnecting. the tire 4 to the channel iron so that the coils of the tireadjacent the. member 7 are held too tightly for free play in order tosecure the proper resilient or cushioning quali- I ties desired, thebolts 7 having nutslO secured upon the inner ends thereof.

A vehicle wheel supplied with a tire constructed in accordance with theforegoing invention is possessed of many advantages from the standpointof resiliency and cushioning qualities, the tire 4 being especiallyadapted to obviate vibration or shock as the wheel turns and passes oversmaller or larger obstacles. V I

It will of course be understood that the number and size of the coils ofthe tire t may be varied, as well as the spaces thcrebetween.

In Fig. 5 is illustrated a modification of the invention in which a rim5 formed with .the variouspanel members 5 and-attached ioo to abroadfelly 3,is' employed: A- plurality of the spring tires 4: would be usedin this construction which is designed for very large vehicle wheels.Any suitable number of the tires 4; could bezutilized according to thedesire of the user, the rim,5 being of courseconstructed accordingly.

,Fig. illustrates a modificationin which the coils or elements of.thetire l ,are provided with projections'or calks 4*, it being ofjoining. the ends ofthe band 6, said ends being overlapped as shown at.6 and one of thefastenings 7 passing through slots in the overlappedends of the band, as shown most clearlyin the drawing.

- Having thus described the invention, what is claimed as new is:

1. In combination with a vehicle wheel embodying a felly, a channel ironapplied -thereto, a tire seated on the channel iron and comprising acoiled body with the innermost ,portions of the coils thereof incontactwith the channel iron, a band passing through the coils of thetire, fasteningsconnecting the band with the telly, and'spacingmeans-1'0 catedbetween the band and the channel iron to prevent unduefriction upon the coils of i the tire. I 9

combination with. a vehicle wheel embodying a telly a channel ironapplied thereto, a tire consisting of a coiled body,

-. the innermost portions of the-coils of which are seated on thechannel iron, a band pass- .ing through the coils of the tire and havingopenings at intervals therein, fastenings at intervals on the felly andprovided with heads interlockin with the band and adapted to passthrough its openings, said fastenings being formed with shoulders atpredetermined distances from the heads and'located between the band andthe channel iron to space the latter parts and prevent unduefrictionup'on the coils of the tire when the fastenings aresecured tothe telly.

3. In combination with a vehicle wheel embodying .a felly, a channeliron secured thereto, a tire consisting of a coiled body,-

the innermost portions of the coils' of which are seated in the channelof the channel iron, a band passing through thecoils and also havingelongated openings at intervals therein, fastening'bolts passing throughthe folly and having heads to pass through the openings of the band andinterlock with the latter,- said bolts being formed with grooves. atopposite sides and spaced from the heads to form seats for certain coilsof the tire, and also having 0 positely projecting shoulders between theand and channel iron to space these parts and prevent undue friction onthe portions of 'the coils of the tire that are received between saidband and channel iron.

In testimony whereof I aflix my signature in presence of two witnesses.
